j IMPROVEMENT IN PLANlNe-MAcHlNEs.

`Specification" formn g part of Letters Patent No. 115,401, dated May30, 1871.

l To all whom t may concern:

Be it known that I, SAMUEL WHITEsIDEs,`

of De Pere, of the county of Brown and State of Wisconsin, have inventedcertain Improvements `in Rotary Planer-Heads, of which the following isaspecification, reference being had to the accompanyingdrawing.

y My invention relates to that cla'ssof wood- `planers in which thecutter consists of a dishV or wheel provided with knives passingtransversely through it, `and which revolves with its side flat againstthe wood, theknives traveling in a circular path over the face of thesame. Theinvention `consists in an improved manner of constructing" thecutter-headV and providing it with two knives or sets of knives, one forroughing off the outsideof the Wood and the other for smoothing orfinishing the surface. i

Figure l is atop-plan view of my cutter-head Fig. 2, a cross-section ofthe same; Fig. 3, av

sectional view of a portion lof the cutterhead, showing the manner ofarranging a pair of like knives Fig. 4:,'across-section of a portionofthe cutter-head enlarged.

. [In constructing my cutter-head I first make l a circular plate ordisk, A, with a central hub,

jc, for attaching it to the shaft or spindle, the

" underside of the hub or central portion being concave so as not tobear on thewood when in operation. The under side of the rim I di-`-vide into two annular concentric faces, c and d, the former horizontalin crosssection and the latter inclined upward and outward atan angleofabout ve degrees, as shown inFigs.

`2 and 4. Through the rim I make two holes,

e and f, one through each of the faces c and d,

and in each of these holes I secure an inclined knife, with itscutting-edge projecting down below the face, as shown. The knife g,which passes through the outer face c, I set so as to project aconsiderable distance below said face, and with its cutting-edgeinclined parallel Vwith the face, or, in other words, with the outerpart of the cutting-edge higher than the inner side. The inner knife h,which passes through the inner and horizontal face d, I set so as toproject very slightly below the same, and with the knife, as wouldotherwise be the case. By

this arrangement I am enabled to produce 'a fine smooth nish to thewood.

Having thus described my invention, what I claim isi The circularplaner-head A, having the annular faces c and d, the outer face d being1nclined at an angle of about five degrees, and both being provided withone or more openings for the reception of the cutters, substantially asdescribed. l
